Cars are very oftensuppliedwithfan cooling with incomplete coverage of a heat exchanger by housing. It allows use anair-stream which runs against the car. Thus we have adecreased efficiency of fan cooling in comparison with the one having completecoverage of the heat exchanger. First of all, it is the result of recirculation of air from under the bonnet space. Influence of recirculation on loss of cooling system effectiveness ishard to define even experimentally. The offereddesign procedure allows making it.
